And yes, I know that when usage gravitates toward something that is
incorrect, the error becomes established after a while. That's part of
the nature of the history of all languages. There are many such
example in English. But I'm an old fuddy-duddy, and I object to such
changes. I know that sooner or later, I'm going to lose on almost all
such issues, but that doesn't mean I have to like them.

The trouble with what he said, above, is that he's using an adverbial
clause as the subject of a sentence. Adverbs should be used to modify
verbs, adjectives, or other adverbs, not as nouns. There are two ways
to say it correctly:

That people call it a modem doesn't make it a modem.

It isn't a modem just because people call it a modem,

Using it the way he does, which is commonplace but incorrect, is
equivalent to using the word modem for things which are not modems, also
commonplace but incorrect.
